Key Features

Massive 9"-10" Front Lift

Provides 9–10 inches of front lift with a 7-inch rear lift for a dramatically taller stance and increased tire clearance.

Heavy-duty subframes and steering knuckles provide the foundation for the lift while the included differential drops help maintain proper 4WD driveline geometry.

MaxTrac Front Struts & Rear Shocks

Includes two 631971 front struts and two 3200LL-4 rear shocks matched to the lifted suspension.

Clears Up to 38" Tires

Designed to clear up to 38x13.50 tires on 8–9" wide wheels. Fender trimming may be necessary depending on the exact wheel and tire combination.
